I have dismantled the lower leg and as replacement servos seems to be hard to get hold of, too expensive to purchase a broken robot for spares. so i have decided to remove the lower arm servo to replace the broken servo in the leg. i was quite surprised to find that these servos are identical.

the main obstacle that i can see is reattaching the four small wires. my first thoughts are to solder these which i am not bad at doing. just a little bit concerned with the small size of the wires.

if anybody has any suggestions maybe a glue that will work or some other way to connect the wires.

i will have a word at work, in the workshop, not sure if they will be able to help as they are used to fixing buses!

will keep you updated with progress if no other suggestions are forthcoming.

please ignor my signature at bottom of post for the minute

surgery is finished, he is all back in one piece. it was the very small plastic gear at the base of the metal gears that had failed. i did wonder why all metal and only one plastic.

i did consider changing gears over however i was under the illusion that they were completely sealed units, but this is not the case as there is two small pins that hold the servo together. one gains access to the gears and one gains access to the motor and electronics.

he can still do 95% of moves, he cant get up on his own and do head stands, but i am quite pleased with the results and maybe this post will help anyone else who comes across this problem.

I found and bought (yes yes) an I-SOBOT 2007, Monday of this week, and I am very happy with the robot, but at night I put the batteries charged and my surprise one of the servo does not work (in the leg right in the center) and search on google and youtube for any track, and nothing but luckily your project has pictures of the servo unarmed, and with operating procedures, disassemble the package and remove the gears, but the test was still not working I realized that the lubrication in the engine was not good and lubricate and operate manually until smooth working, reassemble it and it's working perfectly, without the help of your experience you shared in this forum, I had not accomplished, again thank you very much.
